Fuel tank breather/overflow
hose
1. Fuel tank breather/overflow hose
2. Clamp
Before operating the motorcycle:
●Check the fuel tank breather/
overflow hose connection.
●Check the fuel tank breather/
overflow hose for cracks or dam-
age, and replace it if damaged.
●Make sure that the end of the fuel
tank breather/overflow hose is not
blocked, and clean it if necessary.
●Make sure that the end of the fuel
tank breather/overflow hose is
positioned inside of the clamp.
ECA11400CAUTION:
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and piston
rings, as well as to the exhaust sys-
tem.
Your Yamaha engine has been de-
signed to use premium unleaded
gasoline with a research octane num-
ber of 95 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand. Use of unleaded fuel
will extend spark plug life and reduce
maintenance costs.
EAU13431
Catalytic converter
This model is equipped with a catalyt-
ic converter in the exhaust system.
EWA10860
WARNING0
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-
ing any maintenance work.

10A. Distance (spring preload)
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload
and thereby harden the suspen-
sion, turn the adjusting nut in di-
rection (a). To decrease the
spring preload and thereby soften
the suspension, turn the adjusting
nut in direction (b).
NOTE:
●Use the special wrench included
in the owner's tool kit to make the
adjustment.
●The spring preload setting is de-
termined by measuring distance
A, shown in the illustration. The
longer distance A is, the lower the
spring preload; the shorter dis-
tance A is, the higher the spring
preload. With each complete turn
of the adjusting nut, distance A
changes by 1.5 mm (0.059 in).
●When measuring distance A, the
rear wheel must be raised off the
ground. (See page 6-36).

WARNING0
This shock absorber contains high-
ly pressurized nitrogen gas. For
proper handling, read and under-
stand the following information be-
fore handling the shock absorber.
The manufacturer cannot be held
responsible for property damage or
personal injury that may result from
improper handling.
●Do not tamper with or attempt
to open the gas cylinder.
●Do not subject the shock ab-
sorber to an open flame or oth-
er high heat sources, otherwise
it may explode due to exces-
sive gas pressure.
●Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
●Always have a Yamaha dealer
service the shock absorber.
Tightening torque:
Locknut:
45 Nm (4.5 m·kgf, 32.5 ft·lbf)
